energy forms
6. Five kinetic
energy forms
Notes:
Forms of Energy
1. [Define and identify energy according to its function]: What
are the two main forms of energy? How are they alike? How are
they different?
2. [Define and identify energy according to its function]: What
are the four main types of potential energy? What are the five
main types of kinetic energy? Compare TWO forms of potential
energy and TWO forms of kinetic energy.
*Energy is the ability to
do work or to make a
change in something
*Work is measured by
multiplying the force
used by the distance
the force was applied
*When work is done on
an object, the amount
of energy it has
changes
*A force must be
applied over a distance
in order to qualify as
work
*The two main forms
of energy are potential
and kinetic
*Potential energy is
energy that is stored in
the position, or
structure of an object
*Kinetic energy is the
motion of waves,
electrons, atoms,
molecules, substances,
and objects.
*Main forms of
potential energy:
chemical, mechanical,
nuclear, gravitational
3. [Explain how the transfer of energy occurs]: How does energy
transform from potential to kinetic? From kinetic to potential?

top three energy producing countries? What are the top three

7. law of
conservation of
energy
*Main forms of kinetic
energy: radiant
(includes light, x-ray,
gamma ray, and radio
waves), heat,
mechanical, sound,
electrical
*Energy is neither
created nor destroyed
*If an object has
energy of motion
(kinetic), that energy
started as a form of
potential energy
*Energy is typically
changing forms from
potential to kinetic as
well as from kinetic
back to potential
*Machines will usually
have a way to covert
energy form to allow
for functioning
*Examples: car engine
changes chemical
potential energy to
mechanical and heat
energy; a blender
changes electrical
energy to mechanical
and heat energy; a tree
changes light energy to
chemical energy

5. [Identify and describe alternative energy resources]: What
two facts stand out regarding renewable energy statistics? What
are the five main types of renewable energy?
6. [Define nuclear energy and research how it can be used
today]: How is nuclear energy created? Where is nuclear energy
used and why?

*The five main types of
renewable energy are:
solar, wind, water,
geothermal, and
bioenergy

*Nuclear energy has
the advantage of not
burning any fuel so
there are no pollutants
released into the air.
*Nuclear energy is
energy that is stored in
the nucleus or center
core of an atom. The
nucleus of an atom is
made of tiny particles
of protons (+ positive
charge) and neutrons
(no charge). The
electrons (- negative
charge) move around
the nucleus. Nuclear
energy is the force that
holds the nucleus
together in an atom.
*Fusion is a way of
combining the atoms
to make a new atom.
*Fission is the term for
splitting an atom into
two smaller atoms. The
two smaller atoms
don't need as much
energy to hold them
together as the larger

atom, so the extra
energy is released as
heat and radiation.
*Nuclear power plants
use the heat released
from fission to make
electricity.
*By
splitting uranium atom
s into two smaller
atoms, the extra
energy is released as
heat.
*Uranium is a mineral
rock, a very dense
metal found in the
ground, and it is nonrenewable. Nonrenewable means we
cannot make more of
the substance.
Currently, it is a cheap
and plentiful fuel
source.
